Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural implements, and particularly relates to a single-plant onion planter. Background Technique

[0002] A single-plant onion planter is a tool for agricultural planting, specifically designed to achieve precise single-plant planting when planting onions. Its main function is to accurately insert onion seedlings into the soil to ensure that each onion plant has sufficient growth space and promote uniform growth. Generally, such a planter includes a tool for inserting into the soil and a position device for fixing the seedlings, which can improve the planting efficiency and reduce the labor intensity of manual operation.

[0003] However, the single-plant onion planter mainly plants onions into the soil manually by the user. In this process, the single-plant planting head needs to be sleeved on the root of the onion through the planting sleeve groove, and then the planting rod is used to press the single-plant planting head into the soil. However, because the planting of onions completely relies on manual operation, in many cases, it is easy to cause the onions to be planted too deep into the soil, which will affect the growth and development of the onions and is likely to hinder the onions from normally absorbing nutrients in the soil. Content of the Utility Model

[0004] The purpose of the utility model is to provide a single-plant onion planter to solve the problem that because the planting of onions completely relies on manual operation, in many cases, it is easy to cause the onions to be planted too deep into the soil, which will affect the growth and development of the onions and is likely to hinder the onions from normally absorbing nutrients in the soil as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A single-plant onion planter, including a planting operation rod and an internally threaded telescopic cylinder arranged at the center of the bottom end of the planting operation rod. A metal planting rod is inserted into the internally threaded telescopic cylinder. An inwardly concave telescopic thread is arranged on the outer wall of the metal planting rod. The thread on the inner wall of the internally threaded telescopic cylinder is screwed with the thread on the outer wall of the metal planting rod. A planting depth limiting device is arranged outside the lower side of the center of the metal planting rod;

[0006] The planting depth limiting device includes a metal limiting bar, an internally threaded height-adjusting sleeve and a rotary damping pad. The internally threaded height-adjusting sleeve is threadedly sleeved on the outside of the metal planting rod. A rotary damping pad is fixed on the outer wall of the top end of the internally threaded height-adjusting sleeve. Metal limiting bars are arranged on the outer walls of the left and right ends at the bottom of the internally threaded height-adjusting sleeve.

[0007] Preferably, the internally threaded height-adjusting sleeve can move up and down on the outside of the metal planting rod through the thread by rotating clockwise and counterclockwise. The inner wall of the rotary damping pad closely adheres to the outer wall of the metal planting rod and generates a rotary resistance.

[0008] Preferably, an internally threaded height-fixing sleeve is arranged on the lower side of the internally threaded telescopic cylinder. The internally threaded height-fixing sleeve is threadedly sleeved outside the metal planting rod, and the thread direction on the inner wall of the internally threaded height-fixing sleeve is opposite to that on the inner wall of the internally threaded telescopic cylinder.

[0009] Preferably, when the internally threaded height-fixing sleeve rotates, it can move up and down outside the metal planting rod through the thread. Rotating operation heads are welded to the outer walls of the left and right ends of the internally threaded height-fixing sleeve, and the rotating operation heads can drive the internally threaded height-fixing sleeve to rotate clockwise and counterclockwise.

[0010] Preferably, a single-plant planting head is arranged at the bottom end of the metal planting rod. A planting sleeve groove is arranged inside the single-plant planting head. The planting sleeve groove is integrally U-shaped, and the opening direction of the U-shaped of the planting sleeve groove is downward.

[0011] Preferably, both the left and right ends of the planting operation rod are arranged as hemispheres. Anti-rust protective paint is sprayed on the outer walls of the planting operation rod and the internally threaded telescopic cylinder.

[0012] Compared with the prior art, the utility model provides a single-plant onion planter, which has the following beneficial effects:

[0013] 1. By adding threads to the outer wall of the metal planting rod of the single-plant onion planter, and also adding a new planting depth limiting device outside the metal planting rod, the device can limit the planting depth of the onion in the soil by the metal planting rod through the single-plant planting head. When the metal planting rod plants the onion into the soil through the single-plant planting head at the bottom end, and when a certain planting depth is reached, the planting depth limiting device will block on the soil surface to prevent the metal planting rod from continuing to penetrate into the soil through the single-plant planting head, avoiding the situation of too deep planting depth of the onion. Moreover, the planting depth limiting device can flexibly change the limiting height on the metal planting rod, so that the limiting depth during planting can be flexibly adjusted according to different onion planting situations, avoiding the situation that the depth of the onion in the planting soil is too deep and affecting the normal growth and development of the onion;

[0014] 2. By improving the structure of the planting rod of the single-plant onion planter, mainly adding threads to the outer wall of the metal planting rod and adding an internally threaded telescopic cylinder at the bottom end of the planting operation rod. The internally threaded telescopic cylinder is threadedly sleeved outside the metal planting rod. By rotating the metal planting rod, it can move up and down in the internally threaded telescopic cylinder, so that the overall length of the planting rod can be flexibly changed. After adjustment, the adjusted length can be locked by the internally threaded height-fixing sleeve, so that the single-plant onion planter can adapt to the operation of people with a variety of different heights, avoiding the situation that the length of the single-plant onion planter is too long or too short and causing soreness in the waist of the user during operation.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides as Figures 1-4The single-plant onion planter shown in the figure comprises a planting operating rod 8 and an internally threaded telescopic cylinder 7 arranged at the center of the bottom end of the planting operating rod 8, a metal planting rod 3 is inserted in the internally threaded telescopic cylinder 7, an inner concave telescopic thread is arranged on the outer wall of the metal planting rod 3, the inner wall thread of the internally threaded telescopic cylinder 7 is screwed with the outer wall thread of the metal planting rod 3, a single-plant planting head 1 is arranged at the bottom of the metal planting rod 3, a planting sleeve groove 2 is arranged inside the single-plant planting head 1, the planting sleeve groove 2 is U-shaped as a whole, and the U-shaped opening direction of the planting sleeve groove 2 is downward, the left and right ends of the planting operating rod 8 are both hemispherical, the planting operating rod 8 and the outer wall of the internally threaded telescopic cylinder 7 are sprayed with anti-rust protective paint, when the single-plant onion planter is used to plant onions, it is first necessary to adjust the total length of the metal planting rod 3 and the internally threaded telescopic cylinder 7 according to the height of the user, so that the adjusted length is more labor-saving when the user uses it. Specifically, it is necessary to rotate the operating rod 8 to adjust the total length of the metal planting rod 3 and the internally threaded telescopic cylinder 7 according to the height of the user, so that the adjusted length is more labor-saving when the user uses it. After the hoe 6 is in the working state, the inner thread height fixing sleeve 5 is driven by the working head 6 to rotate, so that the inner thread height fixing sleeve 5 moves downward on the outside of the metal planting rod 3. Then, it is necessary to hold the inner thread telescopic cylinder 7 and rotate the metal planting rod 3, so that the metal planting rod 3 can move up and down in the inner thread telescopic cylinder 7 through the thread. This will change the total length of the metal planting rod 3 and the inner thread telescopic cylinder 7. When the length reaches the optimal labor-saving length, it is necessary to rotate the inner thread height fixing sleeve 5 in the opposite direction until the inner thread height fixing sleeve 5 is tightly against the bottom end of the inner thread telescopic cylinder 7. This will prevent the rotation between the inner thread telescopic cylinder 7 and the metal planting rod 3. Then, the user can hold the planting operating rod 8 and connect the single-plant planting head 1 to the root of the green onion through the planting sleeve groove 2, and then press the green onion root into the soil through the single-plant planting head 1. After reaching the planting depth, pull the single-plant planting head 1 back upward to make it separate from the soil. In this way, the green onion will be planted in the soil to achieve the purpose of planting.

[0022] like Figure 1 , Figure 3 and Figure 4As shown in the figure, a planting depth limiting device 4 is provided on the outside of the lower side of the center of the metal planting rod 3. The planting depth limiting device 4 includes a metal limiting bar 9, an internally threaded adjusting sleeve 10 and a rotary damping pad 11. The internally threaded adjusting sleeve 10 is threadedly sleeved on the outside of the metal planting rod 3. A rotary damping pad 11 is fixed on the outer wall of the top end of the internally threaded adjusting sleeve 10. Metal limiting bars 9 are provided on the outer walls of the left and right ends of the bottom of the internally threaded adjusting sleeve 10. The internally threaded adjusting sleeve 10 can move up and down on the outside of the metal planting rod 3 through the thread by rotating clockwise and counterclockwise. The inner wall of the rotary damping pad 11 closely adheres to the outer wall of the metal planting rod 3 and generates a rotary resistance. An internally threaded height fixing sleeve 5 is provided on the lower side of the internally threaded telescopic cylinder 7. The internally threaded height fixing sleeve 5 is threadedly sleeved on the outside of the metal planting rod 3. The thread direction of the inner wall of the internally threaded height fixing sleeve 5 is opposite to that of the inner wall of the internally threaded telescopic cylinder 7. When the internally threaded height fixing sleeve 5 rotates, it can move up and down on the outside of the metal planting rod 3 through the thread. Rotary operation heads 6 are welded on the outer walls of the left and right ends of the internally threaded height fixing sleeve 5. The rotary operation heads 6 can drive the internally threaded height fixing sleeve 5 to rotate clockwise and counterclockwise.

[0023] As Figure 1 , Figure 3 and Figure 4 shown in the figure, when it is necessary to plant scallions in batches, the planting depth limiting device 4 can be used to limit the depth of scallions planted in the soil, so that the depths of the scallions planted in large quantities are kept consistent, in order to improve the planting effect of scallions and also increase the survival rate of scallions. During specific adjustment, the internally threaded adjusting sleeve 10 needs to be rotated by driving the metal limiting bar 9, which will cause the internally threaded adjusting sleeve 10 to move up and down on the outside of the metal planting rod 3 until the length between the outer wall of the bottom end of the internally threaded adjusting sleeve 10 and the bottom end of the single-plant planting head 1 is equal to the planting depth to be limited. Then, the rotation of the internally threaded adjusting sleeve 10 can be stopped. At this time, the rotary damping pad 11 will prevent the rotation of the internally threaded adjusting sleeve 10 through the generated resistance, so that the internally threaded adjusting sleeve 10 is locked in the current position. After the single-plant planting head 1 presses the roots of the scallions into the soil through the planting sleeve groove 2, when the metal limiting bar 9 blocks on the soil surface, it will prevent the metal planting rod 3 from continuing to penetrate into the soil, so that the planting depth of the scallions can be limited, and the depths of the scallions planted in large quantities can be kept consistent, avoiding the situation that the planting depth of the scallions is too deep and affecting the normal growth of the scallions.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
